The is based on the no arbitrage principle and on rational expectations. The previous hypothesis is called the pure expectations hypothesis . The expectations hypothesis, assuming risk-neutral investors and the term premium , is called the expectations hypothesis, assuming the liquidity preference . The effect of this hypothesis is that the forward rate should be an unbiased predictor for the future spot interest rate due the specified time in the forward contract.


The deficit must be covered by additional borrowing or by printing money. If the government borrows additional money, it will increase the demand for funds and thus push up interest rates. If the government prints money, there will be increased inflation, which will also increase interest rates.

For our purposes, in which we confirmed that the series were nonstationary and that their common equilibrium is stationary, we can run the VEC model. VEC models restrict the long-run behavior of the endogenous variables in the way of limitation by the correction term. Observed time series behave according to a cointegration relationship, but this relationship is constantly changing. In other words, error correction models provide as a first step the cointegration equation , which is corrected with the VAR of the correction term . Nonstationary time series can have a common stationary equilibrium .

Rational Expectations – Imperfections in the Processing of Information

Their residuals must be tested to be i.i.d (difference between the spot interest rates and three-month lagged forward interest rates, or longer further lags for longer FRA maturities). The Johansen cointegration test indicates the total number of possible cointegration vectors. However, there is another interesting concluding remark for the Polish samples of the time series.

Economics cannot always be used to fully determine what society should do. A normative statement is “the system of public education in this country generates greater benefits to society than the cost of running the system.” e. Decrease; Less A decrease in the liquidity premium means that the company can issue debt at a lower interest rate. In contrast, if perceived liquidity of a firm’s debt falls, it’ll have to pay a higher interest rate due to a higher liquidity premium.

What is the Expectations Theory?

The impact of the peso problem on the real bo nd market is much lower than was introduced. But many authors, mainly from Central European countries, solve similar impacts of Eurozone problems and EU fiscal decisions impacts. Investors prefer to be liquid at all times in order to have the freedom to choose whether to spend or invest their funds. Should investors choose to tie up their money in an investment, they would demand to be compensated for the illiquidity that comes with investment. Should they tie up their money longer and longer, they would demand that they be increasingly compensated, in terms of higher yield, for their increasing illiquidity. Under this theory, therefore, we conclude that the Yield Curve would have a notable upward bias.

For all of the time series analyzed, we are unable to reject the null hypothesis regarding the 0.05 statistical significance of the existence of the unit root . Moreover, for all of these time series, we confirm the hypothesis about the abnormal values of particular time series (Jarque-Bera test). Needless to say, even the logs of the time series do not reject the ADF hypothesis. All of the time series observed are not of the first order of integration. The interest rates and forward interest rates are even in their logarithms nonstationary. Notably, the use of unit root tests to distinguish between trend and difference stationary data has become an essential tool in applied research in the last few decades.

Disadvantages of Expectations Theory

Because this does not begin and end in a specific time frame, it is referred to as an ongoing process. Trading forex on margin carries a high level of risk and may not be suitable for all investors. CFDs are complex instruments and come with a high risk of losing money rapidly due to leverage.

The expectations hypothesis has been advanced to explain the 1st 2 characteristics and the premium liquidity theory have been advanced to explain the last characteristic. The market segmentation theory explains the yield curve in terms of supply and demand within the individual segments. Economists who believe in rational expectations base their belief on the standard economic assumption that people behave in ways that maximize their utility or profits. Economists have used the concept of rational expectations to understand a variety of situations in which speculation about the future is a crucial factor in determining current action. curves are usually upward sloping, but short-term interest rates are as likely to fall as to rise. So, this prediction of the expectations theory is inconsistent with the real world evidence. The local expectations form of the pure expectations theory recognizes that in the long term interest rate and reinvestment risks are important.


The yield curve changes because a component of the supply and demand for short-term, medium-term, and long-term bonds varies somewhat, independently. For instance, when interest rates rise, the demand for short-term bonds increases faster than the demand for long-term bonds, flattening the yield curve. Such was the case in 2006, when T-bills were paying the same high rate as 30-year Treasury bonds. On the data sample of 4,028 observations from 2003 to 2019, we run statistical tests available in the EViews statistical software for the nonstationary time series to confirm/reject the EH.

Investing may be an art, but even the greatest artists have a strong understanding of the science at the foundation of their craft. Let’s explore the theory, understand what it teaches us, and where it falls short in practice. A) According to the expectation theory, the long-term spot interest rate is an average of the short-term spot interest rate and the short-term future… Monetary PolicyMonetary policy refers to the steps taken by a country’s central bank to control the money supply for economic stability. For example, policymakers manipulate money circulation for increasing employment, GDP, price stability by using tools such as interest rates, reserves, bonds, etc. It gives a fair understanding of the interest rates to the investors willing to invest in any type of bonds, short term or long term.

The presented conclusion is not too surprising because we observe many shapes in yield curves in general. The problem of panel cointegration really arises with the assumption of homogeneity of regressor coefficients. In this case, the estimated residues for any element of the panel may be marked as non-stationary, even though they are cointegrated. For these reasons, it is necessary to perform several statistical tests based on residual testing for the absence of time series cointegration that will not depend on regressor coefficients.

The difference between these two economic variables is the term premium. It is not hard to see that the pure expectations theory is similar to a pure intellectual exercise. It is rare to achieve the perfect results of this theory where today’s predicted rates over different maturities exactly match future realized spot rates. Since we noted that all maturities are equivalent in function, the slope is equally likely to be upwards as downwards (in tune with the boom-bust cycle, and rising and falling future rate expectations.), but this is not the case. Clearly, investors attach a higher risk to longer maturities due to some intrinsic factor not explained or predicted by the pure expectations theory. The NBP’s strategy is to maintain price stability, presenting the views on price stability and economic growth developments that shape short-term rate policy.

In other words, if investors are going to hold onto a long-term bond, they want to be compensated with a higher yield to justify the risk of holding the investment until maturity. The main empirical conclusion of this paper is that we can create a model of the forward interest rate to the spot interest rates corresponding by the day to maturities for every particular country analyzed . The only suitable method for those nonstationary time series is the VEC method. From the long-period point of view, only in the UK is the increasing yield curve confirmed. The predictable options for term premiums in the long run are also confirmed.

The “policy ineffectiveness” result pertains only to those economic policies that have their effects solely by inducing forecast errors. Many government policies work by affecting “margins” or incentives, and the concept of rational expectations delivers no policy ineffectiveness result for such policies. In fact, the idea of rational expectations has been used extensively in such contexts to study the design of monetary, fiscal, and regulatory policies to promote good economic performance. Increase; More If a company uses debt for a buyout, both its debt load and the chances of defaulting on making committed payments will increase. In such a situation, yields will increase and it will be more expensive for a company to borrow money from bond markets.


For example, if inflation and the real risk-free rate were constant, a positive maturity risk premium would likely increase over time, which would lead to an upward-sloping yield curve. An upward-sloping yield curve could indicate a positive maturity risk premium, but it also could indicate increased inflation expectations. If there is no maturity risk premium, expectations about future short-term interest rates determine the yield curve’s shape. The upward slope indicates that future short-term rates are expected to be greater than current short-term rates. The aim of this paper was to decide whether or not term premiums appear and thus are predictable in Central European countries in the data samples of forward rate agreement interest rates and corresponding spot interest rates. On the data sample of 4,028 observations from 2003 to 2019, we ran statistical tests available in the EViews statistical software for the nonstationary time series to confirm/reject the EH.

  • Life insurance companies prefer to invest in long-term bonds to match their long-term liabilities, while real estate companies prefer to issue long-term bonds due to their long project cycles.
  • True Actions that lower short-term interest rates will not necessarily lower long-term rates, because long-term rates are not affected as much as short-term rates by the Fed’s intervention.
  • In further research, this problem is technically solvable thanks to nonlinear equilibrium adjustments methods.
  • Equalization of expected returns means that investors’ forecasts become built into or reflected in the prices of stocks.

With this information, we can use the Unbiased Expectations Theory to predict what the one-year bond’s interest rate will be next year. Of the country, then the bond market, prices, and yield will definitely take a hit and change accordingly. The formula for calculation remains the same as the expectations theory.
